WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 697,803, dated April15, 1902. Application filed October 11, 1901. Serial No. 78,294. (Nomodel.)

To (6 whom it nuty concern:

Be it known that I, JOHN CAMPBELL, a citizen of the United States,residing at No. 3830 lVilliams street, in the city of Denver,county ofArapahoe, and State of Colorado, have invented certain new and usefulImprovements in VVater-Closets, of which the following is aspecification.

My invention relates to that class of waterclosets in which a hinged panis employed at the bottom of the bowl, the same being capable of beingflushed or filled with water to close the bottom of the bowl, and inwhich a hinged seat and lid or cover are connected with the pan tooperate the same and with the flushing-valve to open it to flush the panand wash the bowl. This closet, although suitable for general use, isdesigned with special reference to the requirements for use uponrailway-cars, and therefore, in addition to other requirements,is madeof avery compact form and with a view to extreme simplicity andcertainty of operation.

-Some of the objects of this invention are, first, to provide awater-closet in which very simple and direct means connect the pan withthe lid and seat to cause the pan to be down when both lid and seat aredown, when both lid and seat are up, or when both lid and seat are beingraised, and to cause the pan to be raised only when the lid is raisedwhile the seat is left down; second, to provide a watercloset in whichthe flushing-valve shall be opened when either.lid or seat is raised orlowered or when both lid and seat are raised or lowered; third, toprovide a water-closet in which the connections from seat and lid to thepan and valve shall be of such construc tion as to be incapable of beingaffected by dirt and corrosion to cause the lid or seat to stick whenpart way down, and thus hold the flush-valve open and waste the limitedsupply of water carried on cars; fourth, to provide a water-closet inwhich the flushing-valve is placed vertical and at such height as todrain into the inlet at the top of bowl and yet have the mechanismsubstantially all below the top surface of the lid, and, fifth, toprovide a water-closet in which all the operating mechanism is simple,durable, all on the outside, easily accessible and taken apart, andconfined to the width and length of a compact form of bowl.

The above objects are attained by means of the mechanism andconstruction illustrated in the accompanying drawings, in which- Figure1 is a side elevation of the closet closed, with the seat and lid downand with the interior of the bowl represented by dotted lines, theconsequent lowered position of the pan being represented by dash-lines.Dot ted lines represent the lid in its tipped-up position, theconnections in their corresponding position, and the pan in itsconsequent upper position is shown by short dotted lines. A portion ofthe corner of lid and seat are broken away to fully show the valve-leverand rolls. Fig. 2 is a rear elevation of the corner of the closet havingthe pan and valve connections, showing the inclined pipe leading fromflushvalve to bowl. Fig. 3 is a side elevation similar to a portion ofFig. 1, showing in full lines the seat down, the lid partly raised, thevalvelever in its depressed position, and the connections and pan intheir consequent positions. Dotted lines represent the seat in apartly-raised position,the connections in their consequent position, andthe pan in its lowered position. Fig. 4 shows an edge View or sideelevation of one of the plates, which are secured to the corner of lidand seat. Fig. 5 is a plan view of one of the plates and its roll. Thetwo plates are very similar.

Similar characters denote like parts in the several views.

In the drawings, A represents the outer casing or shell, and B the innerportion of the same, constituting the bowl proper. These may be formedof such shape as is desired and integral with each other or fittedtogether, as may be deemed expedient. The material may be of anysuitable substance, but is preferably of porcelain. Secured to the upperrear part of the casing A in any desirable manner, as by screws orbolts, is the framecasting O, which supports the pieces to which theseat and lid or cover are hinged, the flush valve, and the valve-leverG. The support for the seat will be designated D, the support for thelid E, and the flush-valve F. The hinges H of the seat and lid are ofthe ordinary form, the plates of the hinges being preferably set inflush with the surface of the seat, as represented. Similar plates, asrepresented in Figs. 4 and 5, are secured in any desired manner, as byscrews, to one rear corner of the seat and to the corner of the lidabove, that for the seat being designated J and the one on the cover I.Each of the plates I and J is formed with a pair of rearwardprojections, between which are revolubly mounted rolls (designated K andL, respectively) for engagement with the valve-lever G. A mere solidprojection without the roll would suffice and be operative; but thebifurcated projection with roll is the preferred construction. Theplates I and J are provided at a point somewhat nearer the center ofwidth of the closet with downward and rearward bifurcated projections Mand N, and in the latter is preferably mounted a freely-revoluble roll0. Though the bifurcated projection and roll are the preferred form, asolid projection of similar form would be equally effective and may besubstituted.

A lever P is freely pivoted upon a suitable pin in the bifurcatedprojection M, and a connection Q is freely pivoted to the lower end ofthe lever P and in a crank R, which is rigidly secured upon therock-shaft S, and to this shaft S is fastened the pan T. The frame 0 hasfront extensions O, which pass through suitable openings in shell A, andto these eX- tensions C are secured bearings 0 in which the rock-shaft Sis freely mounted.

The flush-valve F is preferably of the form having within it a springfor the return of the valve proper to its closed position, as in Fig. 1,and the outlet-tube of the valve passes through a suitable hole throughcasting C and is secured in place by a lock-nut F. (Seen in Fig. 2.) Ashort declining pipe F is connected to the outlet-tube of valve F andpasses into the shell A through a suitable boss A to admit the waterfrom the flushvalve F to the bowl B, from which it descends into the panT when in its upper position.

Freely pivoted upon a suitable screw U in the upper extremity of castingO is the valvelever G, which rests upon the valve-stem F the depressionof the lever causing the opening of the valve, as shown in Fig. 3. Theforward end of the lever Gr is providedv with inclined faces upon itsupper surface, there being preferably a pair of the inclined faces G andG slanting in opposite directions and in position to be engaged by theroll K of the lid and a similar pair of inclined faces in position to beengaged by the roll L of the seat, that the front end of the lever G maybe depressed by the tipping up or down of either the lid or the seat,and consequently opening the flush-valve. The closet would beefiectively operative if the lever G were provided only with inclinedfaces to be engaged by the roll K of the lid, but the closet would notthen be as thoroughly washed.

The pan T is tipped from its lower to its upper dotted position (seeFig. 3) by tipping the lid only from its lower to its upper dottedposition, and in so tipping the lid the lever P is drawn over the roll0, which acts as a fulcrum, and the lower end of the lever is inconsequence forced backward and the connection Q swings or raises thecrank R and the pan T, as represented by the dotted lines. In case theseat is raised simultaneously with the lid,then the roll 0 is swungforward out of position to act as a fulcrum for the lever P, andconsequently the pan is left in its lower position, as shown by dottedlines in Fig. 3. The location of the rolls K and L may be said to beeccentric to the hinges of the seat and cover or lid. The roll 0 andpivoting of lever P in plate I may be said to be pendent to the hingingof the seat and cover, respectively, as they swing a short distance pastthe vertical in both directions. The lever P and connection Q may besaid to constitute a twopart jointed bent connection from the pancrank Rto a pivot of the cover located eccentric to the cover-hinge and adaptedto operate the pan coincident with the tipping of the cover when thisjointed connection is sufficiently bent.

The water-supply pipe is connected to the bottom of the flush-valve, itsposition being denoted by the dotted lines in Fig. 1. The object of thepair of oppositely-inclined faces of the lever G to be engaged by theroll or projection of the lid or seat is that the valvelever may be bothdepressed and released by one continuous movement of the lid or seat ineither direction.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a water-closet, the combination with a hingedcover, of a roll on said cover adapted to swing from the hinge centerwith the cover; a flush-valve located below the surface of the saidcover; a lever adapted to open said valve and provided with oppositeinclined faces projecting into the path of movement of the said swingingroll; and a descending, selfdraining pipe connection from the said valveto the flushing-entrance of the closet-bowl.

2. In a water-closet, the combination, with a flush-valve, of a leveradapted to open said valve; a hinged cover and seat; rolls upon saidcover and seat, adapted to swing from their hinge centers; andoppositely-inclined faces upon the valve-lever, projecting into the pathof movement of the rolls of the cover and seat.

3. In a water-closet, the combination, with a pan supported by arock-shaft and crank, of a hinged cover; a lever pivoted to said covereccentric to its hinge; a connection from said lever to said rock-shaftcrank; and afulcrumbearing in position and adapted to engage the saidlever as the cover is tipped.

4. In a water-closet, the combination, with a dump-pan supported by arock-shaft and crank, of a hinged cover; a lever pivoted to the covereccentric to its hinge; a connection from said lever to said rock-shaftcrank; a hinged seat; and a fulcrum secured to said seat pendent to itshinge, and in position to engage said lever.

5. In a water-closet, the combination, with a dump-pan, of a hingedcover; a lever and connection from said cover to said pan; and a hingedseat having a fulcrum projection located in position and adapted to beswung out of position to engage said lever when said cover and seat aresimultaneously tipped.

6. In a water-closet, the combination, with a hinged cover and hingedseat, of a dumppan; a lever pivoted to said cover and connected withsaid pan; a fulcrum on said seat in position and adapted to engage saidlever; and a flush-valve operatively connected with said cover.

7. In a water-closet, the combination, with a hinged cover and a hingedseat, of a flushvalve and valve-lever having inclined faces; projectionsupon said cover and seat in position and adapted to operate said valveby ongaging said faces; and connections from said cover to said pan,adapted to sustain the pan in its upper position when the cover is upand the seatis down.

8. In a water-closet, the combination, with a flush-valve andvalve-lever, of a hinged cover in operative engagement with said lever;a cover-lever pivoted eccentric to the cover-hinge; a dump-pan connectedwith the cover-lever; a pendent fulcrum controlled by a hinged seat; anda descending pipe connection from the flush-valve to the entrance of thecloset-bowl.

In testimony whereof I have hereunto set my hand and affixed my seal,before two subscribing witnesses, at Denver, Colorado, this 7th day ofOctober, A. D. 1901..
